目标:
1)弄清楚nova组件通过packstack安装后源码位置
2)确定nova组件服务启动路径
3)确定nova组件配置文件路径

3 nova组件配置文件路径
[root@localhost bin]# cd /etc/nova
[root@localhost nova]# ls
api-paste.ini migration nova.conf policy.json release rootwrap.conf
总结:
通过packstack安装的nova组件:
源码在: /usr/lib/python2.7/site-packages/nova
启动服务在: /usr/bin
配置文件在: /etc/nova
参考:
基于packstack安装queen版本的openstack |
